vlan simulator

Recently, I have participated in many discussion and evaluation activities on hospital network solutions. Almost all hospital solutions use VLAN technology, however, I found that VLAN design in most solutions has a common and fatal defect, that is, the core of VLAN spanning network. This article will talk about your views on this issue for your reference.VLAN mut

This article introduces the optimal performance of a vswitch in VLAN application configuration. The content of this article is as follows: filtering service function, Layer 2 network layer switch, Layer 3 network layer switch, data frame inbound, VLAN tag, below are some examples of different forms of switch VLAN applications. Filter service features: The filter

There are four ways to divide VLANs: 1. VLAN division by port Many VLAN manufacturers use the ports of vswitches to divide VLAN members. The configured ports are all in the same broadcast domain. For example, Ports 1, 2, 3, 4, and 5 of A vswitch are defined as virtual network AAA. Ports 6, 7, and 8 of the same vswitch form the virtual network BBB. In this way, c

For static and dynamic vlan configuration code instances of Huawei switches, there are many methods for configuring vlan of Huawei switches. Below is a sample code for vlan configuration of Huawei switches, I hope it will be helpful to the fans. either static or dynamic must be selected, followed by the vlan configurat

VLAN (virtual local area network), is based on the Ethernet interactive technology to build a fictitious network, can either divide the same physical network into multiple valn, can also cross the physical network barriers, users in different subnets to the same VLAN. Figure 2 is an example of a VLAN partition. Figure 2 There are many ways to implement VLANs,

The switch is not designed to be used as a security device, and its function is still to improve network performance. If the switch is to be part of the security mechanism, if the switch is to be properly configured first, then the manufacturer of the switch will have a complete understanding of the basic standards of the switch software and the implementation of these standards.If you have strict network security requirements, or do not use a shared switch, you should use a dedicated switch to

This paper mainly introduces the implementation of the 802.1Q VLAN protocol in the Ethernet switch, and some basic contents of the 802.1P protocol, details of the implementation of the two Protocols, and reference data of the 802.1Q and 802.1P protocols. First, 802.1Q protocol 802.1Q protocol, that is, Virtual bridged local area networks protocol, the main provisions of the VLAN implementation, below we f

size, you might as well use a switch to create VLANs.Management of VLANsVLANs are inextricably linked to switched networks, but implementing VLANs will redefine the management environment. VLAN-defined logical domains involve possible views of the network, so the network management platform can display IP images, and sometimes images based on IPX are displayed. If you deploy a VLAN, its topology may not ma

First, there may be many reasons for this problem, but in most cases it is caused by inconsistent SDK and ADT versions. At the beginning of Android development, ADT Bundle was directly downloaded from Android Developers. Its ADT version is 22.3. Later, the SDK automatically updated to 22.6, but the ADT was not updated, therefore, the above problems occur. Directly update the ADT to solve the problem. The ADT update method is as follows: Http://blog.csdn.net/shengxia0dubing/article/details/213342

MUX VLANPrinciple:Devices within the same subnet (IP level), but not the same VLAN (2, 3, 10), can be used to adjust the role of the VLAN to communicate or not communicate, save IPTwo major classes of VLANs: Primary VLAN (primary interface), sub-VLAN (Group VLAN and isolated

When you configure VLANs in a virtualized environment, you need to understand the differences between VLANs and virtual VLANs on the physical switch to better configure the network.First look at the link type on the physical switch.Three types of links on the upper port of the switch: Access, trunk, Hybird.A port of type access can only belong to 1 VLANs and is typically used to connect to a computer's port;Trunk type port can allow multiple VLANs through, can receive and send multiple
